Templates of factors

During the development of multicellular organisms, both transient and stable gene expression patterns have to be established in a precisely orchestrated sequence. Evidence from diverse model organisms indicates that this epigenetic program involves not only transcription factors, but also the local structure, composition, and modification of chromatin, which define and maintain the accessibility and transcriptional competence of the nucleosomal DNA template.

Translation initiation of hepatitis C virus (HCV) occurs through an internal ribosome entry site (IRES) located at its 5¢-end. As a positive-stranded RNA virus, HCV uses its genome as a common template for translation and replication, but the coordination between these two pro-cesses remains poorly characterized.

Abstract X-ray crystal structure determination of agglutinin from abrus precatorius in Taiwan is presented. The crystal structure of agglutinin, a type II ribosome-inactivating protein (RIP) from the seeds of Abrus precatorius in Taiwan, has been determined from a novel crystalline form by the molecular replacement method using the coordinates of abrin-a as the template. The structure has space group P41212 with Z = 8, and been refined at 2.6 Å to R-factor of 20.4%. The rootmean-square deviations of bond lengths and angles from the standard values are 0.009 Å and 1.3°.
